Study Notes
Surveying Instruments
-
Total Station: Combines electronic theodolite (measures angles) and electronic distance measuring (EDM) device (measures distances)
- Used for topographic and cadastral surveys.
- Essential for setting out construction projects and land surveys.
- Captures 3D data and creates digital terrain models (DTMs).
- Directly transfers data to computers for analysis.
-
GPS (Global Positioning System): Satellite-based system for precise positioning and location data.
- Used for large-area geodetic surveys.
- Critical for accurate location mapping in cadastral and engineering surveys.
- Valuable in remote areas where traditional equipment is less practical.
- Commonly used in agricultural surveys and land development.
-
Theodolite: Precision instrument for measuring horizontal and vertical angles.
- Primarily used in engineering and topographical surveys.
- Measures angles between ground points.
- Useful in construction, road design, and geodetic surveys
-
Steel Tape: Flexible metal tape for measuring distances (30m-100m).
- Used in cadastral surveys for short distances or boundary lines.
- Ideal for elevation and horizontal distance measurements on relatively flat terrain.
- Common in land surveys and construction site measurements
-
Fiberglass Tape: Lightweight fiberglass tape, less prone to rust compared to steel tape.
- Suitable for longer distance measurements in land surveys.
- Preferred in topographic and engineering surveys due to its lightness and flexibility.
- Beneficial for use in rough or difficult terrain.
-
Level: Instrument to determine horizontal planes.
- Uses spirit level for accurate elevation difference measurements.
- Crucial in levelling surveys for height differences and reference points.
- Commonly used in construction for vertical alignment, foundations and roadway alignment.
- Applicable for grading in civil engineering projects like drainage systems.
-
Levelling Rod: Graduated rod for measuring height differences with a level.
- Used with a level to establish elevation differences between points.
- Common in topographical surveys and construction for precise elevation readings.
- Often used to measure water levels in hydrographic surveys.
